Anti-5G Base Station Interference Analysis and Practice of C-band Medium Wave Broadcasting Transmitting Station

介绍中波广播转播台卫星接收系统的工作原理,着重介绍高频头、接收机等设备,分析5G基站对C频段卫星接收系统产生干扰的原因,并分析其对高频头、接收机等设备产生的干扰,从3个方面提出切实可行的中波广播转播台抗5G基站干扰的改造措施,结合抗5G基站干扰的具体措施进行详细说明,指出改造时需要注意的两点问题,为今后各个中波广播转播台对C频段卫星接收设备进行改造提供借鉴和参考。

This paper introduces the working principle of the satellite receiving system of the medium wave broadcasting relay station,focuses on the equipment such as the high frequency head and receiver,analyzes the causes of the interference of the 5G base station to the C-band satellite receiving system,analyzes its interference to the high frequency head,receiver and other equipment,and puts forward practical and feasible transformation measures of the medium wave broadcasting relay station against the interference of the 5G base station from three aspects,This paper describes in detail the specific measures of our station against the interference of 5G base station,and points out two problems that need to be paid attention to in the transformation,so as to provide reference and reference for the transformation of C-band satellite receiving equipment by various medium wave broadcasting and broadcasting stations in the future.
